When a combination of the technical solutions is contradictory or unattainable, the combination of the technical solutions neither exists nor falls within the protection scope of the appended claims of the present disclosure.

[0033] The present disclosure provides a table top range hood. As illustrated in FIG. 1 to FIG. 7, in some embodiments, the table top range hood includes a duct housing 1100 having an air inlet 1111, the air inlet 1111 facing a first orientation; a light-transmitting cover 1510 being connected to the duct housing 1100 and defining an accommodation cavity 1600 together with the duct housing 1100; and a light-emitter 1520 disposed in the accommodation cavity 1600 and adapted to emit light, the light emitted by the light-emitter 1520 being adapted to pass through the light-transmitting cover 1510 and irradiate towards the first orientation.

[0034] By disposing the light-emitter 1520, the air inlet 1111 opens towards the first orientation and the light emitted by the light-emitter 1520 irradiates towards the first orientation. In this way, a user can easily observe an extraction effect, providing reference for adjusting a position of the table top range hood. Further, by disposing the light-emitter 1520, the table top range hood is suitable for use in the outdoor without lights or under low-light conditions. In addition, the light-emitter 1520 is disposed in the accommodation cavity 1600 defined by the light-transmitting cover 1510 and the duct housing 1100 to prevent the light-emitter 1520 from being contaminated by the fume. Compared with cleaning the light-emitter 1520, it is easier to clean the light-transmitting cover 1510.

[0035] In an exemplary embodiment of the present disclosure, the table top range hood includes a range hood body 1000 and a machine body 2000. The range hood body 1000 is mounted at the machine body 2000. The machine body 2000 of the table top range hood is placed on a table, so that the range hood body 1000 is maintained at a predetermined distance from the table top. An assembly between the range hood body 1000 and the machine body 2000 can be referred to in the related art, which is not an improvement of the present disclosure, and thus will not be described in detail.

[0036] The range hood body 1000 includes the duct housing 1100, a support 1200, a fan 1300, the light-transmitting cover 1510, and the light-emitter 1520. The duct housing 1100 is provided with an air duct 1110. The duct housing 1100 may be integrally formed or may be formed by connecting at least two parts. The air duct 1110 has an end constituting the air inlet 1111 and another end constituting an air outlet 1112. The support 1200 is disposed in the air duct 1110 and fixed through connecting to the duct housing 1100. There are many connection methods between the support 1200 and the duct housing 1100, such as welding, screwing, and engagement. It should be understood that the support 1200 is a component for supporting other parts. The support 1200 may be processed by metallic materials or other materials. The support 1200 may have a regular shape or an irregular shape. In this embodiment, the support 1200 is a sheet metal part, and the so-called sheet metal part is processed by a sheet metal process. The fan 1300 is connected to the support 1200 so as to be fixed. In this case, the fan 1300 is located in the air duct 1110 and is located between the air inlet 1111 and the air outlet 1112. The fan 1300 drives the fume to enter the air duct 1110 from the air inlet 1111 and to be discharged from the air outlet 1112.

[0037] The air inlet 1111 opens towards the first orientation. For example, taking the user facing the air inlet 1111 as a reference, a side of the table top range hood facing the user is the front, a side facing away from the user is the rear, a side corresponding to the left hand of the user is the left, a side corresponding to the right hand of the user is the right, a side close to the table top is the lower, and a side facing away from the table top is the upper. The first orientation points to a front space of the table top range hood. That is, the table top range hood extracts the fume from the front space by the air inlet 1111.

[0038] The light can pass through the light-transmitting cover 1510. That is, the light-transmitting cover 1510 has a transparent or translucent structure. The light-transmitting cover 1510 is connected to the duct housing 1100, enabling the accommodation cavity 1600 to be formed between the light-transmitting cover 1510 and the duct housing 1100. The light-emitter 1520 is disposed in the accommodation cavity 1600. The light-emitter 1520 is a component that can emit the light. For example, with a common light-emitter 1520 as a lamp bead, the light-emitter 1520 can emit the light when the lamp bead is energized. The light emitted by the light-emitter 1520 can pass through the light-transmitting cover 1510 and irradiate towards the first orientation (i.e., irradiate towards the front space of the table top range hood). It should be understood that since the air inlet 1111 opens towards the first orientation, when the table top range hood is in operation, the fume is extracted and flows from a space indicated by the first direction (the front space of the table top range hood) to the air inlet 1111. In this case, the light emitted by the light-emitter 1520 passes through the light-transmitting cover 1510 and irradiates towards the space indicated by the first direction (the front space of the table top range hood). The light can be reflected and refracted when passing through the light-transmitting cover 1510. Due to presence of a large number of oil mist particles in the fume, the light encounters these particles and undergoes reflection and refraction, in such a manner that the user can observe a flow direction of the fume and the extraction effect of the fume is visually presented to the user.

[0039] It should be understood that since the table top range hood is easy to carry, it is necessary to adjust the table top range hood to a suitable position when using the table top range hood. Through the above arrangement, since the user can directly observe the extraction effect of the fume, adjusting the table top range hood to the suitable position can be facilitated for the user. Precisely, by disposing the light-emitter 1520, which is suitable for use in the outdoor without lights or a dim environment, a lighting effect can also be provided.

[0040] It should be noted that the table top range hood can produce oil adhesion during extracting the fume. In this embodiment, the light-emitter 1520 is disposed in the accommodation cavity 1600 defined by the light-transmitting cover 1510 and the duct housing 1100. It is difficult for the fume to enter the accommodation cavity 1600 to prevent the light-emitter 1520 from being contaminated by the fume. Even if the fume contaminates the light-transmitting cover 1510, it is much more convenient for the user to clean the light-transmitting cover 1510 than to clean the light-emitter 1520.

[0041] As illustrated in FIG. 1, FIG. 2, FIG. 6, and FIG. 7, in some embodiments, the air inlet 1111 is surrounded by the accommodation cavity 1600. In this way, the light can be emitted towards the first orientation in a direction surrounding the air inlet 1111, improving coverage of the light. Therefore, flow of the fume can be easily observed when the fume is extracted. Since the accommodation cavity 1600 is defined by the light-transmitting cover 1510 and the duct housing 1100, the light-transmitting cover 1510 also needs to surround the air inlet 1111. For example, in the structure illustrated in FIG. 2, the light-transmitting cover 1510 is of a circular ring shape and mounted at an air inlet end of the duct housing 1100. When the light-emitter 1520 emits the light, the table top range hood can form a light-emitting ring to improve an irradiation range of the fume, further facilitating observation of the flow of the fume for the user.

[0042] Further, on the premise that the light-transmitting cover 1510 is also designed to surround the air inlet 1111, as illustrated in FIG. 1, FIG. 2, FIG. 6, and FIG. 11, in some embodiments, the light-transmitting cover 1510 is tapered in a flow direction of fume, which can provide flow guidance for the fume entering the air inlet 1111, reducing turbulence at the air inlet 1111, and thus is conducive to improving the extraction effect of the fume and reducing noise.

[0043] As illustrated in FIG. 1, in some embodiments, the light-emitter 1520 is of a strip shape and is arranged in an extension direction of the accommodation cavity 1600.

[0044] In an exemplary embodiment of the present disclosure, the strip-shaped light-emitter 1520 constitutes a lamp strip, which may include a plurality of lamp beads. The light-emitter 1520 is arranged in the extension direction of the accommodation cavity 1600, that is, surrounding the air outlet 1112. Therefore, a corresponding light source exists in the direction surrounding the air outlet 1112, to emit the light passing through the light-transmitting cover 1510, further improving intensity of light emission, which is more conducive to improving an illumination effect.

[0045] As illustrated in FIG. 6, FIG. 7, FIG. 9, and FIG. 10, in some embodiments, the duct housing 1100 has a recess 1140. The light-transmitting cover 1510 covers the recess 1140 and defines the accommodation cavity 1600 together with the recess 1140. The light-emitter 1520 is connected to a recess wall of the recess 1140.

[0046] In an exemplary embodiment of the present disclosure, with reference to an orientation illustrated in FIG. 10, the recess 1140 of the duct housing 1100 opens towards the front. During assembly, the light-emitter 1520 can be connected to the recess wall of the recess 1140 to realize fixation of the light-emitter 1520. Then, the light-transmitting cover 1510 can be connected to the duct housing 1100 and cover the recess 1140 to define the accommodation cavity 1600 between the light-transmitting cover 1510 and the duct housing 1100 (the recess 1140 is at least part of the accommodation cavity 1600) to form protection for the light-emitter 1520. It can be understood that the light-transmitting cover 1510 is a separate component to be mounted last. The light-emitter 1520 is first connected to the recess wall of the recess 1140 to be fixed, so as to facilitate wiring and power supply.

[0047] Further, as illustrated in FIG. 10, in some embodiments, the recess wall of the recess 1140 includes a recess bottom wall 1141 and recess side walls 1142 respectively located at two opposite sides of the recess bottom wall 1141. Therefore, an opening is formed between the recess side walls 1142 on the two opposite sides of the recess bottom wall 1141. As illustrated in FIG. 10, the recess 1140 has an opening and opens towards the front. The light-emitter 1520 is mounted at the recess side wall 1142 at one side of the two opposite sides of the recess bottom wall 1141. For example, the light-emitter 1520 is mounted at the recess side wall 1142 at a lower side of the orientation illustrated in FIG. 10, and emits the light towards the recess side wall 1142 at another side of the two opposite sides of the recess bottom wall 1141 (a recess side wall 1142 at an upper side). The light emitted by the light-emitter 1520 is reflected by the recess side wall 1142 at the other side of the two opposite sides of the recess bottom wall 1141 (the recess side wall 1142 at the upper side) and irradiates towards the first orientation. The light emitted by the light-emitter 1520 is further diverged after being reflected, improving light emitting uniformity of the light-transmitting cover 1510.

[0048] As illustrated in FIG. 1 to FIG. 7, in some embodiments, the duct housing 1100 includes a first housing 1120 and a mounting frame 1130, and the mounting frame 1130 is connected to an inner wall of the first housing 1120 and the air inlet 1111 is surrounded by the mounting frame 1130. The light-transmitting cover 1510 connects to the mounting frame 1130 and defines the accommodation cavity 1600 together with the mounting frame 1130.

[0049] In an exemplary embodiment of the present disclosure, the first housing 1120 constitutes a majority of the duct housing 1100. The mounting frame 1130 is connected to an inner wall of an air inlet end of the first housing 1120. The light-transmitting cover 1510 is connected to the mounting frame 1130. The mounting frame 1130 and the first housing 1120, as independent components, are connected and fixed to each other by means of a connection method. By designing the mounting frame 1130 as an independent component, mounting of connection structures at the mounting frame 1130 can be facilitated, especially in a case where various types of connection structures are disposed at the mounting frame 1130. Compared to integral forming of the mounting frame 1130 and the first housing 1120, this embodiment can effectively reduce manufacturing complexity. Further, when it is necessary to mounted other parts to an inside of the first housing 1120, the mounting frame 1130 may be connected to the first housing 1120 after mounting of these parts, so as to avoid interference.

[0050] There are various ways to connect the mounting frame 1130 to the first housing 1120. For example, the mounting frame 1130 is snap-connected to the first housing 1120, which is quick and easy without direct manipulation by the user as long as the mounting frame 1130 is controlled to align with a corresponding position of the first housing 1120 to move into place until the snap-connection occurs. In addition, since the mounting frame 1130 is connected to the inner wall of the first housing 1120, the connection structures between the mounting frame 1130 and the first housing 1120 can be concealed once the snap-connection is performed, which can avoid exposure of a connection mechanism. Similarly, the light-transmitting cover 1510 may also be designed to be snap-connected to the mounting frame 1130.

[0051] As illustrated in FIG. 1 to FIG. 8 and FIG. 12 to FIG. 13, in some embodiments, the table top range hood further includes a filter 1400 configured to filter the fume. The filter 1400 is located at a flow path of the fume. For example, the filter 1400 is disposed at an air inlet 1111. When the fume enters the air inlet 1111, the fume flows through the filter 1400 and is filtered by the filter 1400, and then flows through the fan 1300 to be discharged. In this embodiment, the filter 1400 is connected to the mounting frame 1130. That is, both the light-transmitting cover 1510 and the filter 1400 need to be connected and fixed to the mounting frame 1130. Since the mounting frame 1130 is the independent component with respect to the first housing 1120, at the mounting frame 1130 can conveniently have a connection structure configured to connect to the light-transmitting cover 1510 and a connection structure configured to connect to the filter 1400.

[0052] The mounting frame 1130 is provided with a first magnetic attraction portion 1132 and a first connection member 1131. The filter 1400 is provided with a second magnetic attraction portion 1440 and a second connection portion 1430. The first connection member 1131 and the second connection portion 1430 are configured to be plug-connected to each other, and the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440 are configured to be magnetically connected to each other, enabling the filter 1400 to be detachably connected to the mounting frame 1130. Through plug-in connection between the first connection member 1131 and the second connection portion 1430, the filter 1400 can be quickly positioned. Through magnetic connection between the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440, further fixation for the filter 1400 can be realized. This structure is simple, effectively improving convenience of disassembly and assembly of the filter 1400.

[0053] The filter 1400 accumulates dirt and may become dirty even clogged after a period of use, hence requiring disassembly of the filter 1400 for cleaning. In the related art, the filter 1400 is fixed by screwing in screws. That is, when installing the filter 1400, screws need to be tightened to fix the filter 1400 in place. When disassembling the filter 1400, the screws need to be loosened. The operation of tightening or loosening screws requires the user to control a screwdriver to turn the screws. Assembly and disassembly experience with this method remains to be improved. Therefore, in this embodiment, the first connection member 1131 is disposed to be engaged with the second connection portion 1430, and the first magnetic attraction portion 1132 is disposed to be engaged with the second magnetic attraction portion 1440.

[0054] When the filter 1400 is mounted to the mounting frame 1130, the second connection portion 1430 is controlled to be engaged with the first connection member 1131. The engagement between the second connection portion 1430 and the first connection member 1131 is realized in a form of plug-in connection. The second connection portion 1430 may be inserted into the first connection member 1131 or the first connection member 1131 may be inserted into the second connection portion 1430. Simply inserting one of the first connection member 1131 and the second connection portion 1430 into another of the first connection member 1131 and the second connection portion 1430 can achieve rapid positioning, which is convenient and quick. For example, when the first connection member 1131 is a socket, the second connection portion 1430 can be inserted into the socket to achieve a quick plug-in connection.

[0055] On a basis of the plug-in connection between the first connection member 1131 and the second connection portion 1430, the second magnetic attraction portion 1440 is controlled to be engaged with and the first magnetic attraction portion 1132. Engagement between the second magnetic attraction portion 1440 and the first magnetic attraction portion 1132 is realized through being magnetically connected to each other. It can be that the first magnetic attraction portion 1132 generates a magnetic field to attract the second magnetic attraction portion 1440, or it can be that the second magnetic attraction portion 1440 generates a magnetic field to attract the first magnetic attraction portion 1132. Alternatively, both the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440 can generate the magnetic field to attract each other. On the basis of the plug-in connection between the first connection member 1131 and the second connection portion 1430, simply bringing the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440 close to each other enables their magnetic attraction connection, which is convenient and quick. For example, when the first magnetic attraction portion 1132 is a magnet, and the second magnetic attraction portion 1440 is also a magnet, both the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440 generate the magnetic field, respectively, to enhance an attraction force of the magnetic attraction connection.

[0056] It is precisely through cooperation of the plug-in connection and the magnetic attraction connection that the disassembly of the filter 1400 is performed very conveniently. When the filter 1400 is removed from the mounting frame 1130, the user grasps the filter 1400 and applies a force. The force applied by the user overcomes the attraction force between the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440 to separate the first magnetic attraction portion 1132 and the second magnetic attraction portion 1440. Then, the second connection portion 1430 is controlled to move in an opposite direction of an insertion direction to separate from the first connection member 1131. In this way, the disassembly of the filter 1400 is completed, facilitating cleaning of the filter 1400.

[0057] As illustrated in FIG. 6 to FIG. 8 and FIG. 12 to FIG. 14, in some embodiments, the second connection portion 1430 is disposed at a side of a center of the filter 1400 and the second magnetic attraction portion 1440 is disposed at another side of the center of the filter 1400. Therefore, when the filter 1400 is mounted to the mounting frame 1130, connection points are formed at two opposite sides of the center of the filter 1400, improving mounting stability of the filter 1400.

[0058] Reference can be made to orientations of FIG. 1, positions of the second connection portion 1430 and the second magnetic attraction portion 1440 may be as follows: the second connection portion 1430 may be disposed at a left side of the filter 1400, and the second magnetic attraction portion 1440 may be disposed at a right side of the filter 1400. Alternatively, the second connection portion 1430 may be disposed at the right side of the filter 1400, and the second magnetic attraction portion 1440 may be disposed at the left side of the filter 1400. Alternatively, the second connection portion 1430 may be disposed at an upper side of the filter 1400, and the second magnetic attraction portion 1440 may be disposed at a lower side of the filter 1400. It should be understood that the first connection member 1131 and the first magnetic attraction portion 1132 need to be disposed correspondingly regardless of where the second connection portion 1430 and the second magnetic attraction portion 1440 are disposed.

[0059] In some embodiments, the second connection portion 1430 is disposed at the lower side of the filter 1400, and the second magnetic attraction portion 1440 is disposed at the upper side of the filter 1400. When the filter 1400 is mounted at the mounting frame 1130, the second connection portion 1430 is controlled to be plug-connected to the first connection member 1131. Since the second connection portion 1430 is located at the lower side of the filter 1400, the user can easily observe a relative position of the second connection portion 1430 and the first connection member 1131, facilitating controlling the engagement between the second connection portion 1430 and the first connection member 1131. After the plug-in connection between the second connection portion 1430 and the first connection member 1131, the filter 1400 can abut against the mounting frame 1130 under an action of the force applied by the user and under an action of gravity. Therefore, the mounting frame 1130 is less likely to be loosened and separated. Further, the upper side of the filter 1400 is controlled to rotate towards the mounting frame 1130 and move closer, allowing the second magnetic attraction portion 1440 to gradually approach the first magnetic attraction portion 1132 until they are magnetically connected, further enhancing convenience of assembly and disassembly.

[0060] As illustrated in FIG. 6 to FIG. 10, in some embodiments, the mounting frame 1130 is provided with a stopper 1133 located downstream of the filter 1400. The stopper 1133 is configured to abut with the filter 1400 during mounting the filter 1400, preventing the filter 1400 from continuing to move towards an inside of the air duct 1110, and strengthening positioning of mounting of the filter 1400.

[0061] In an exemplary embodiment of the present disclosure, it can be seen from the above that positioning can be provided only when the first connection member 1131 is engaged with the second connection portion 1430. By disposing the stopper 1133, the stopper 1133 can abut with the filter 1400 during the mounting of the filter 1400 to prevent the filter 1400 from continuing to move along the air duct 1110, facilitating alignment between the first connection member 1131 and the second connection portion 1430, which can strengthen the positioning. Since the stopper 1133 can abut with the filter 1400, the first magnetic attraction portion 1132 can be disposed at the stopper 1133. The filter 1400 and the stopper 1133 can be magnetically attached together when the filter 1400 and the stopper 1133 come into contact with each other.

[0062] As illustrated in FIG. 8, in some embodiments, the first connection member 1131 is the socket. The second connection portion 1430 is inserted into the socket. The second connection portion 1430 has an oil discharge opening 1431. The filter 1400 is configured to discharge oil through the oil discharge opening 1431.

[0063] In an exemplary embodiment of the present disclosure, during extracting the fume by the table top range hood, filtration of the fume by the filter 1400 can produce the oil at the filter 1400. The oil is a complex mixture including various organic matters and water. The oil flows downwardly along the filter 1400 under the action of gravity, and is discharged through the oil discharge opening 1431 by disposing the oil discharge opening 1431 at the second connection portion 1430 on the basis that the second connection portion 1430 is inserted into the first connection member 1131 (the socket). It should be understood that the table top range hood includes an oil cup 2400 configured to be detachable. The oil discharged from the oil discharge opening 1431 finally enters the oil cup 2400 for temporary storage. The oil cup 2400 is designed to be detachable. When the table top range hood is used, the oil generated by the table top range hood is temporarily stored in the oil cup 2400. When the oil cup 2400 needs to be cleaned, the oil cup 2400 can be removed from the table top range hood to allow the oil to be poured. After cleaning of the oil cup 2400 is completed, the oil cup 2400 can be remounted back into the table top range hood.

[0064] As illustrated in FIG. 12 to FIG. 15, in some embodiments, the filter 1400 includes a filter screen 1410 and a filter screen frame 1420. The filter screen frame 1420 has an oil collecting groove 1427. The second connection portion 1430 is disposed at the filter screen frame 1420. In addition, the oil discharge opening 1431 is in communication with the oil collecting groove 1427. The filter screen 1410 is disposed in the filter screen frame 1420 and located in the oil collecting groove 1427.

[0065] In an exemplary embodiment of the present disclosure, the filter screen frame 1420 is a skeleton structure of the filter 1400 and configured to support the filter screen 1410. The filter screen 1410 is disposed at the filter screen frame 1420 to be supported. The filter screen 1410 has a porous structure, which can not only allow the fume to flow, but also filter the fume to obtain the oil. In this embodiment, the filter screen frame 1420 has an oil collecting groove 1427. In addition, the filter screen 1410 is located at the oil collecting groove 1427, and the filter screen 1410 is surrounded by the oil collecting groove 1427. When the filter screen 1410 filters the fume to obtain the oil, the oil flows along the filter screen 1410 until the oil enters the oil collecting groove 1427. By disposing of the oil collecting groove 1427, the oil separated from the filter screen 1410 is collected and then is discharged from the oil discharge opening 1431.

[0066] As illustrated in FIG. 12 to FIG. 16, in some embodiments, the filter screen frame 1420 includes a first frame 1421 and a second frame 1422. The first frame 1421 and the second frame 1422 are connected to each other to clamp the filter screen 1410 to support the filter screen 1410. In addition, after the first frame 1421 and the second frame 1422 are connected and fixed to each other, the oil collecting groove 1427 is defined between the first frame 1421 and the second frame 1422. In this way, assembly between the filter screen frame 1420 and the filter screen 1410 can be facilitated on the basis of forming the oil collecting groove 1427. For example, an assembly process between the filter screen frame 1420 and the filter screen 1410 is as follows: the filter screen 1410 is placed at the first frame 1421, and then the second frame 1422 is controlled to be connected to the first frame 1421. After the second frame 1422 and the first frame 1421 are connected and fixed to each other, the filter screen 1410 can be fixed and the oil collecting groove 1427 can be defined, in this case the filter screen 1410 is located in the oil collecting groove 1427.

[0067] The first frame 1421 can be connected to the second frame 1422 in many methods as long as connection and fixation between the first frame 1421 and the second frame 1422 can be ensured. For example, to improve convenience of connection between the first frame 1421 and the second frame 1422, the first frame 1421 and the second frame 1422 are fixed with screws. As illustrated in FIG. 17 and FIG. 18, one of the first frame 1421 and the second frame 1422 has an insertion slot 1423, and another of the first frame 1421 and the second frame 1422 is provided with a plug-in portion 1424. When the first frame 1421 is connected to the second frame 1422, the plug-in portion 1424 is inserted into the insertion slot 1423. On this basis, one of the first frame 1421 and the second frame 1422 is provided with a snap-fit 1425, and the other of the first frame 1421 and the second frame 1422 is provided with a snap-fit position 1426. When the first frame 1421 is connected to the second frame 1422, the snap-fit 1425 is snap-connected to the snap-fit position 1426. Assembly positioning is realized by cooperation between the plug-in portion 1424 and the insertion slot 1423. Further, fixation is realized by cooperation between the snap-fit 1425 and the snap-fit position 1426.

[0068] It should be understood that one of the first frame 1421 and the second frame 1422 has the insertion slot 1423, and the other of the first frame 1421 and the second frame 1422 is provided with the plug-in portion 1424. That is, when the first frame 1421 has the insertion slot 1423, the second frame 1422 is provided with the plug-in portion 1424 correspondingly. When the first frame 1421 is provided with the plug-in portion 1424, the second frame 1422 has the insertion slot 1423 correspondingly. When the first frame 1421 is provided with both the insertion slot 1423 and the plug-in portion 1424, the second frame 1422 is provided with the plug-in portion 1424 and the insertion 1423 correspondingly. The same is true for arrangement of the snap-fit 1425 and the snap-fit position 1426.

[0069] Since the second connection portion 1430 is disposed at the filter screen frame 1420, and the filter screen frame 1420 includes the first frame 1421 and the second frame 1422 connected to each other, to facilitate communication between the oil discharge opening 1431 and the oil collecting groove 1427, as illustrated in FIG. 17 and FIG. 18, the second connection portion 1430 has one part disposed at the first frame 1421 and another part disposed at the second frame 1422. For example, part of the second connection portion 1430 and the first frame 1421 are integrally formed. The other part of the second connection portion 1430 and the second frame 1422 are integrally formed. When the first frame 1421 and the second frame 1422 are connected and fixed to each other to define the oil collecting groove 1427, the part of the second connection portion 1430 is engaged with the other part of the second connection portion 1430 to define the oil discharge opening 1431.

[0070] As illustrated in FIG. 13 and FIG. 14, in some embodiments, the second magnetic attraction portion 1440 is disposed between the first frame 1421 and the second frame 1422. For example, the second magnetic attraction portion 1440 is fixed to either of the first frame 1421 and the second frame 1422, which provides physical protection for the second magnetic attraction portion 1440. Therefore, the second magnetic attraction portion 1440 is less likely to be misplaced during the disassembly and the assembly of the filter 1400 for cleaning.

[0071] As illustrated in FIG. 12, in some embodiments, the filter 1400 is further provided with a handle 1428. For example, the handle 1428 is disposed at the filter screen frame 1420 and provides a force point for the user to grasp, facilitating applying force to the filter 1400 for the user to complete the disassembly and the assembly of the filter 1400.

[0072] Although some embodiments of the present disclosure are described above, the scope of the present disclosure is not limited to the embodiments. Under the concept of the present disclosure, any equivalent structure transformation made using the contents of the specification and the accompanying drawings of the present disclosure, or any direct or indirect application of the contents of the specification and the accompanying drawings of the present disclosure in other related fields, shall equally fall within the scope of the present disclosure.
